Venturi Meter Book

A venturi meter with a 3 in.

Service nozzle isuzu panther. Applicable to the cases of very large tubes and of a small value only of the liquid to be gauged paperback. When the flow goes through the contraction it must speed up and so the pressure must drop. Its basic principle is also depends on the bernoulli equation ie.

By measuring the two pressures engineers can directly calculate the velocity of the fluid. Velocity increases pressure decreases. It basically works on the principle of bernoullis theorem.

Venturimeter is an application of bernoullis equation. A venturi meter is a device that allows flow rates through pipes to be calculated by measuring the difference in pressure created by a contraction in a pipe. However the same principle can be exploited with only minimal pressure loss with the use of a venturi meter.

Venturi meter is a measuring or also considered as a meter device that is usually used to measure the flow of a fluid in the pipea venturi meter may also be used to increase the velocity of any type fluid in a pipe at any particular point. The corresponding velocity of fluid are v 1 and v 2. Diameter throat is installed in a 6 in.

An instrument making use of a new method of gauging water. The pressure at the entrance to the meter is gauge and it is undesirable that the pressure should at any point fall below absolute. In this case the meter consists of a.

The principle of venture meter is firstly developed by gb. To find the coefficient of discharge for orifice meter. Knowing the pipe diameter this velocity can be.

Assuming that for the meter is 096 find the maximum flow for which it may be used. As i already told that venturi meter works on bernoullis principle so lets find out how it depends on bernoullis principle. The venturi meter is connected to a pipe at two points as shown in the fig.

Fm 308 flow measurement by venturi and orifice meter objectives. Suppose the quantity of liquid v1 enter to the pipe as per continuity equation volume flow rate at the inlet q1 is equal to discharge at the outlet q2 so if v1 amount of water enters to the inlet of the venturi meter the same amount of water should be. Venturi in 1797 but this principle comes into consideration with the help of c.

Venturi meter and orifice meter are the commonly used flow meters for measuring massvolumetric flow rate or velocity of the flowing fluid. Take the specific weight of the liquid as and.
